Tidskriftsartikel (refereegranskat)abstract
- We investigate the survival performance of new technology-based firms (NTBFs) over the business cycle and compare them against other entrepreneurial firms. Our data comprise the entire population of entrepreneurial firms entering the Swedish economy from 1991 to 2002, which we follow until 2007. Discrete-time duration models are employed to investigate whether the business cycle impacts differently on the survival likelihood of NTBFs vis-A -vis other entrepreneurial firms. Our main findings are three. First, NTBFs generally experience a lower hazard rate compared to other entrepreneurial firms, which is interpreted as a sign of their high 'quality.' Second, all entrepreneurial firms are sensitive to and follow a pro-cyclical pattern of survival likelihood over the business cycle. Three, when comparing NTBFs with the broader group of other entrepreneurial firms, we find that NTBFs are more sensitive to business cycle fluctuations. The above results come with a qualification, though. The sensitivity during the business cycle mainly pertains to self-employed NTBFs. Also, NTBFs' higher survivability is only linked to not being characterized as self-employed.

Home, Sweet Home: Returns to Returning in the Age of Mass Migration
- 2022
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Studying migrants from Sweden to the United States, we provide new evidence on return migration during the Age of Mass Migration. Focusing on a sample of migrants and stayers observed in childhood, we document limited effects on income and occupational upgrading, but large effects on wealth. Male returnees held about twice as much wealth as stayers and about 40 percent more than staying brothers. These effects were likely driven by accumulated savings overseas, rather than inheritance or an income premium back home. For female returnees, wealth effects are of similar magnitude, but appear to be realized primarily through marriage.

How important are local inventive milieus: The role of birthplace, high school and university education
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Using data on the entire population in combination with data on almost all individuals in Sweden listed as inventors, we study how the probability of being listed on a patent as inventor is influenced by the density of other future inventors residing in the same region. In this process, we control for demographic and sector effects along with the educational characteristics of parents. This approach allows us to trace how location history influences individuals' inventive capacity. We focus on three types of influences: (a) future inventors in the municipality around the time of birth, (b) future inventors around the time of graduation from high school and (c) future inventors at graduation from higher education. We find suggestive evidence that co-locating with future inventors may impact the probability of becoming an inventor. The most consistent effect is found for place of higher education; some positive effects are also evident from birthplace, whereas no consistent positive effect can be derived from individuals' high school location. Therefore, the formative influences mainly deriving from family upbringing, birth region and from local milieu effects arising from a conscious choice to attend a higher education affect the choice of becoming an inventor.

Innovation in Malmö after the Öresund Bridge
- 2022

Tidskriftsartikel (refereegranskat)abstract
- We analyze the effect of the Öresund Bridge, a combined railway and motorway bridge between Swedish Malmö and the Danish capital Copenhagen, on inventive activity in the region of Malmö. Applying difference-in-difference estimation on individual-level data, our findings suggest that the Öresund Bridge led to a significant increase in the number of patents per individual in the Malmö region as compared with the two other major regions in Sweden, Gothenburg, and Stockholm. We show that a key mechanism is the attraction of highly qualified workers to the Malmö region following the construction of the bridge.

Invention, Innovation and Regional Growth in Swedish Regions

Ingår i: Uddevalla Symposium 2009. The Geography of Innovation and Entrepreneurship. - Trollhättan : Högskolan Väst. - 9789163355714 ; , s. 449-467

Konferensbidrag (refereegranskat)abstract
- We explore the link between invention and innovation on the one hand and the level of economic activity and economic growth in Sweden by using patents granted and the quality of patens as our indicators of invention and innovation respectively. Our results indicate that both types of measures are able to explain the level and the changing levelof economic activity equally well. However, an important difference is that the economic activity is affected differently by the two measures. We find that inventions have the strongest marginal effect in regions where economic activity is the highest. Instead, innovations have similar marginal effects across regions with different economic activity. Our interpretation is that quality-adjusted patents sort out "bad" from "good" patents in a manner which reflect economic importance.
